Granted: 1992-09-08
Abstract: ABSTRACT OF THE DISCLOSURE      TELEPHONE INDEX            The telephone index has a plurality of selection keys and a spring-operated drawer with a stack of index cards, which is held in the index housing by means of a locking device in such a way that on operating a selection key the drawer locking means is released and consequently the drawer with the selected index card and the index cards below it is extended, whilst the index cards located above the selected card are held back in the index housing by means of a card hold-back device released by the operated selection key and is constructed in such a way that the unlocking of the drawer on operating a selection key takes place by a drawer position change in such a way that in its front region the drawer is lowered counter to the tension of a spring element and simultaneously the drawer locking means is released on the upper edge of the housing opening for the drawer, so that the drawer can be extended, the drawer locking means comprising a stop cam shaped onto the upper edge of the front drawer terminal ledge and which ensures that in the inserted state the drawer is held in the index housing.

Patent CA-1332510-C (CA)
Inventor: MCMASTER HAROLD A
IPC: C03B27/04
Filed: 1987-05-06
Granted: 1994-10-18
Abstract: A furnace (12) including a roller convey-or (18) and gas burners (20) distinct from the conveyor for supplying forced convection that is the dominant mode of heat transfer to glass sheets during a heating process. The gas burners (20) have general utility but have particular utility when utilized in a closely spaced relationship to the roller conveyed glass sheets to provide the forced convection heating. Each burner (20) includes a combustion member (38) in which gas and air are introduced in a tangential relationship with respect to its inner surface to provide a swirling motion that mixes the gas with the air for combustion prior to discharge through outlets (46) to provide the forced convection heating. A glass sheet heated by this gas burner forced convection on the roller conveyor and subsequently cooled has reduced roll-wave distortion and reduced edge distortion as compared to radiantly heated glass sheets.

Title: 2-hydrocarbyl-3,6-dichloropyridines and their preparation
Inventor: HALPERN MARC E
IPC: C07D213/61
Filed: 1987-09-04
Granted: 1993-03-23
Abstract: ABSTRACT 2-Hydrocarbyl-3,6-dichloropyridines are prepared from dichloromethyl hydrocarbyl ketones and acrylonitrile in a two-step process involving an addition reaction under basic conditions to form intermediate 1,1-dichloro-3-cyanopropyl hydrocarbyl ketones and a subsequent cyclization reaction in the presence of hydrogen chloride.  Thus, 3,6-dichloro-2-methylpyridine is prepared from 1,1-dichloro-2-propanone and acrylonitrile by the formation and further reaction of 4,4-dichloro-5-oxo-hexanenitrile. The intermediates and products are novel compounds useful in the preparation of herbicides and nitrification inhibitors.   34,270A-F

Title: Aerosol delivery article
Inventor: ROBERTS DONALD L
IPC: A24D1/22
Filed: 1988-01-22
Granted: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE      An aerosol delivery article is capable of producing substantial quantities of smoke, both initially and over the useful lifetime of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products or sidestream smoke.  The article also delivers very low levels of carbon monoxide.  The article is able of providing the user with the sensations and benefits of cigarette smoking without burning tobacco.  The article includes a carbonaceous fuel element, an aerosol forming substance within a heat conductive container, an outer member surrounding the heat conductive container, and a mouthend piece.  Upon draw on the mouthend piece air enters the peripheral region of the outer member and enters the heat conductive container. As the heat conductive container is in a heat exchange relationship with the fuel element, aerosol is thereby formed within the container and passed to the mouth of the user.

Title: Smokeless pyrolysis furnace with single thermocouple, and ramp and soak temperature control system
Inventor: KOPTIS ROBERT A
IPC: F23N5/10
Filed: 1988-03-10
Granted: 1991-06-04
Abstract: SMOKELESS PYROLYSIS FURNACE WITH SINGLE THERMOCOUPLE, AND RAMP AND SOAK TEMPERATURE CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE   A batch-type pyrolysis furnace fired by a main heat source such as a gas burner or an electric heating coil in combination with an afterburner to burn volatiles generat-ed in the furnace's main chamber, is operated to inciner-ate high-polymer loads smokelessy, yet is effectively safeguarded from explosions. A single thermocouple (zone TC) senses the instantaneous temperature in a critical sensitive zone (CSZ) of the furnace and in cooperation with a programmable controller (PC), maintains a presel-ected ramp and soak temperature profile over the entire burn cycle. The CSZ has been found to be within about 1' (foot) from the upper edge of the throat, and not lower than about 6" (inches) from the ceiling of the main chamber. When the temperature required by the profile is exceeded, a single water spray actuated by a signal from the PC lowers the temperature below the profile. The zone TC thus maintains a fire under controlled temperature conditions in the main chamber without an explosion, using a single TC in the control system.

Abstract: Abstract of the Disclosure:          An improved latch assembly having a latch body adapted to be coupled to a generally fixed support, such as a chassis unit, wall or post.  The latch body has a groove for removably receiving a retained pin which is adapted to be mounted on a movable structural member to be latched, such as a door, support arm, gate or the like.  The latch body further includes a latch pin which is spring biased into engagement with the retained pin when the retained pin is received in the groove of the latch body.  The inter-engagement of the retained pin and latch pin is such that the retained pin is restricted against movement in three mutually perpendicular directions, namely the x, y and z directions.  The retained pin has a pair of spaced, cylindrical parts on opposite sides of a pair of beveled parts which converge toward each other to an annular junction therebetween.  The latch pin has a conical end portion for engaging the beveled parts of the retained pin to resist axial movement of the retained pin in the z direction.  The engagement of the cylindrical parts of the retained pin with the surfaces of the latch body defining the groove resists movement of the retained pin in a pair of mutually perpendicular directions, namely the x and y directions.

Title: Analog floppy disk data separator
Inventor: WAHLER RICHARD E
IPC: G11B20/14
Filed: 1988-10-05
Granted: 1992-12-08
Abstract: ABSTRACT OF THE DISCLOSURE     A floppy disk data separator includes a phase lock loop which locks onto a clock signal that is synchronized to the data stream being read from the disk.  The clock signal is derived from a sync counter which is reset each time a data bit is received from the disk. The output of the sync counter is an edge delayed by 1/4 of a bit time.  The next edge of the clock occurs each 1/2 bit time after that until the next data bit is received.  These clock signals are phase compared with clock signals produced in the phase lock loop to synchronize the clock to the disk data.  In another aspect of the invention, the phase lock loop is operated in either a low-gain or high-gain mode.
